This product is a custom-made bag using Dyneema®︎ Composite Fabric DCF (formerly Cuben Fiber) print, designed for the Evernew 400FD. The size is just right, not too tight or too loose. When taking out the cup, it's easiest to push it up from the bottom. The fabric thickness is 1.0oz. It has a flashy, unique pattern that's super cute. Since there's no other pattern like it, please consider purchasing if it catches your eye. A large OD can (250) will also fit, so it can help prevent rust inside your cooker. It's a good size and convenient to have one. I can't make many, so please don't hesitate if you're interested.
